Name Description
Error check
Error
processing
Corrective action
• Change the slot of the servo
amplifier whose load is large.
• Reduce the load.
• Reexamine the operation pattern.
• Servo amplifier having large load is
adjacent.
• Use a servomotor whose output
is large.
• Repeat acceleration/deceleration
and perform automatic tuning.
• Servo system is instable and hunting.
• Turn OFF automatic tuning and
make gain adjustment manually.
2053
(Note-1)
Multiple axis
overload
• Encoder cable and power cable (U, V, W)
coming out of one servo amplifier are
connected to the incorrect servomotor.
• Make correct connection.
2054
(Note-1)
Servo
amplifier
alarm
• Alarm occurred in one or more axes of
the servo amplifier installed to the base
unit (MR-J2M-BU) for servo amplifier.
Immediate
stop
• Remove the alarm causes of all
servo amplifiers where alarm has
occurred.
2086
RS232
communicatio
n error
• Serial communication error occurred
between servo amplifier and
communication device (parameter unit
or personal computer).
• Check for disconnection of the
cable.
• Replace the communication
devices.
2102
Battery
warning
• The voltage of the battery installed in the
servo amplifier has become low.
• Replace the battery.
2103
Battery
disconnection
warning
• The power supply voltage to the
absolute position encoder become low.
• Replace the battery.
• Check the encoder cable for
wire breakage.
• Replace the servomotor.
• Replace the servo amplifier.
2140
Excessive
regeneration
warning
• An excessive regeneration error [2030]
may be occurred (regeneration level of
85[%] of the maximum load capacity for
the regenerative resister has been
detected).
• Refer to the details on the
excessive regeneration error
[2030].
2141
Overload
warning
• An overload error [2050], [2051] is likely
to occur (85[%] of overload level has
been detected).
Operation
continues
• Refer to the details on the
overload errors [2050], [2051].
2143
Absolute
position
counter
warning
• Absolute position encoder pulses faulty. Operation
continues.
Home position
return request
ON
(Note-2)
• Take noise suppression
measures.
• Replace the servomotor.
• Execute the home position return
after measures.
2146
Servo forced
stop
• Servo amplifiers are forced stop state.
(Servo amplifier input signal EM1 is
OFF.)
• Ensure safety and release the
forced stop.
2147
Emergency
stop
• An emergency stop (EMG) signal input
from the Multiple CPU system.
Immediate
stop
• Ensure safety and release the
emergency stop.
2149
Main circuit
OFF warning
• The servo ON (SON) signal turned on
while the contactor turned off.
• The main circuit bus voltage fell to 215
[V] or lower at 50 [r/min] or lower.
Any time during
operation
Operation
continues
• Turn on the main circuit
contactor or circuit power
supply.
